Frequently Asked Questions

1) Which power system studies does Keentel perform? ▼

Keentel performs load flow, contingency, short-circuit and duty analysis, protection coordination, arc-flash, harmonic and power quality studies, motor starting, voltage drop, transient stability where applicable, and grounding studies. We tailor the study set to the system voltage class (EHV, HV, or MV), facility type, and specific regulatory and utility requirements.

2) Why are short-circuit studies critical for EHV, HV, and MV systems? ▼

Short-circuit studies confirm equipment interrupting ratings and momentary withstand capabilities. They also define protective device settings, ensure breaker duty compliance, and reduce the risk of catastrophic equipment failure. These studies are often required for utility approval and safe long-term operation.

3) What is the difference between coordination studies and arc-flash studies? ▼

Coordination studies ensure protective devices operate selectively and quickly for electrical faults. Arc-flash studies estimate incident energy exposure and define PPE boundaries and equipment labeling requirements. Because coordination directly impacts arc-flash results, Keentel typically performs these as an integrated workflow to balance safety and system selectivity.

4) How does Keentel evaluate harmonics and power quality? ▼

We model harmonic sources such as inverters, variable frequency drives, and large rectifiers, calculate distortion levels at key buses, and verify compliance with applicable limits, often IEEE 519 or specific utility requirements. If mitigation is required, we evaluate filter options, transformer configurations, and system impedance changes to develop a practical solution.

5) Can Keentel study weak grid and inverter-based resource interconnections? ▼

Yes. Weak grid conditions affect voltage stability, fault response, and protection performance. Keentel evaluates short-circuit ratio, reactive power margin, voltage regulation, and control interactions to recommend mitigation such as STATCOMs, synchronous condensers, or tuned control strategies to ensure stable and compliant operation.

6) What data does Keentel need to begin a power system study? ▼

Typically required information includes one-line diagrams, equipment ratings, transformer impedances and tap settings, cable and conductor data, protective device details, load profiles, generator or inverter parameters, and utility source equivalents. Keentel can also work with partial data early in a project and refine models as detailed design progresses.

7) How do you ensure study results are defensible for utility and ISO review? ▼

Keentel documents assumptions, model sources, and validation checks throughout the analysis process. We provide clear base case descriptions, sensitivity runs, and traceable references to equipment data sheets. Deliverables are formatted to match common utility and ISO expectations to reduce review cycles and approval delays.

8) How are study results converted into actionable design changes? ▼

We translate study results into specific design actions such as breaker upgrades, relay setting updates, CT and PT changes, cable sizing adjustments, reactive compensation sizing, filter selection, or layout modifications. The true value is not just the report itself, but the practical engineering decisions supported by detailed analysis.
